SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 415,898, dated November 26, 1889.

Application filed June 25, 1889. Serial No. 315,461. (No model.)

To all whom it may concern:

3e it known that we, HENRY PURNELL BULLooH and WILLIAM LEONARD GROGAN, both of Jonesborough, in the county of Coryell and State of Texas, have invented a new and Improved Sash-Holder, of which the following is a full, clear, and exact description.

The invention relates to windows provided with uncounterbalanced sashes; and its object is to providea new and improved sashholder which is simple and durable in construction and permits of conveniently lowerin g the upper sash and raising the lower sash, or raising both the lower and upper sashes to any desired place in the window-frame.

The invention consists of a spring secured to the lower sash and pressing with its free end on the upper sash.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate correspondingparts in both the figures.

Figure 1 is a front view of the improvement as applied, and Fig. 2 is an enlarged transverse section of the same on theline J51 of Fig. 1.

The Window A is provided with the upper sash B and the lower sash G, mounted to slide in the usual guideways formed in the windowframe D. The sashes B and O are uncounterbalanced, and in order to hold the sashes in any desired position we provide one or more sash-holders E, two being illustrated in Fig. 1.

Each sash-holder is provided with a spring F, secured at the upper end of the lower sash C, preferably at one or bot-h sides thereof. The free end of the spring F rests against the upper sash B, the spring F being bent upward gradually, as shown in Fig. 2. In order to decrease the frictional contact between the free end of the spring F and the upper sash B, we preferably provide the free end of the said spring with a friction-roller G, traveling on the side of the upper sash B.

It will be seen that the upper sash B is held in an uppermost position by the spring F pressing against the said sash with sufficient force to prevent its sliding down. Vhen the operator pulls the sash B down to the desired place, the spring F permits such movement; but as soon as the operator releases the upper sash the spring holds the sash in place in any posit-ion in which it may be placed. hen the lower sash is moved upward, the free end of the spring F travels on the upper sash B, and, on account of being held in contact with the said upper sash, it presses the lower sash G into firm contact with its guideways, so that. the lower sash is held in whatever position it is raised to. It will further be seen that the spring F has the tendency to press the upper sash outward against its guideways while the lower sash is pressed inward, whereby all rattling of the two sashes is prevented.

On the spring F is secured a small spring H, which extends rearward and presses against the collar I of a transversely-extending pin J, preferably passing through the spring H and through the spring F. On the outer end of the pin J is secured a knob K, and the inner end of the said pin is adapted to engage an aperture L formed in the upper sash B. The aperture L is located in such a relative position to the pin J that the latter can engage the aperture only when the two sashes B and C are closed, as shown in Figs. 1 and 2. This pin J, when engaging the aperture L in the upper sash B, locks the sashes in place.

Then the operator desires to open either the lower or upper sash, he pulls on the knob K, so that the pin J is disengaged from the aperture L, after which the lower sash is raised or the upper sash pulled down, as above described.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. The combination, with the upper and lower sashes, of a spring secured to the lower sash and provided with a friction-roller on its free end engaging the upper sash, substantially as described.

2. In a sash-holder, the combination, with the upper and lower sashes, of a spring secured by one end to the lower sash and pressing with its other end on the upper sash,and

a spring-pressed pin held on the said spring apertured near its free end, and the pin J, and adapted to engage an aperture in the passing through the said springs and pro- IO upper sash, subtantially as shown and devided with the collar I, as set forth.

3. As an improved article of manufacture, WILLIAM LEONARD 'GROGAN.

a sash-fastener consisting of the apertured Vitnesses:

spring F, provided With the friction-roller G, COLUMBUS A. SHORT,

the spring H, secured to the spring F and JOHN T. JONES.
